3-D magnetic field of coils with an open metallic core in boundary-integral approach K. Pawluk Department of Fundamental Research in Electrotechnics, Institute of Electrical Engineering, 04-703 Warsaw, ul Pozaryskiego 28, Poland ABSTRACT Boundary-integral approach to 3-D stationary magnetic fields exited by coils and/or current-carrying rings is presented. Metallic elements placed variously in neighbours of the coils are considered like inner boundaries for outer magnetic field. The boundary-integral model is formulated for indirect boundary quantities: monopole and/or dipole surface densities of the 'magnetic charge'. The author's BIMS package has been performed. Some results of computation of the magnetic field in an open magnetic core put inside or outside of the coils, axially or not, are presented. The original post-processing of the package affords possibilities to accomplish the particular design, rather untypical in engineering practice. This is a matter
